tmp_table_size can now be set to 0 (to disable in memory internal temp tables) Improved speed for internal Maria temp tables: - Don't use packed keys, except with long text fields. - Don't copy key all accessed pages during key search. Some new benchmark tests to sql-bench (for group by) BUILD/compile-pentium64-gcov: Update script to use same pentium_config flags as other tests BUILD/compile-pentium64-gprof: Update script to use same pentium_config flags as other tests include/my_sys.h: Added count of my_sync calls mysql-test/r/variables.result: tmp_table_size can now be set to 0 sql-bench/test-select.sh: Added some new test for GROUP BY on a not key field and group by with different order by sql/mysqld.cc: Added count of my_sync calls tmp_table_size can now be set to 0 (to disable in memory internal temp tables) sql/sql_select.cc: If tmp_table_size is 0, don't use in memory temp tables (good for benchmarking MyISAM/Maria temp tables) Don't pack keys for Maria tables; The 8K page size makes packed keys too slow for temp tables. storage/maria/ma_key_recover.h: Moved definition to maria_def.h storage/maria/ma_page.c: Moved code used to simplify comparing of identical Maria tables to own function (page_cleanup()) Fixed that one can read a page with a read lock. storage/maria/ma_rkey.c: For not exact key reads, cache the page where we found key (to speed up future read-next/read-prev calls) storage/maria/ma_search.c: Moved code to cache last key page to separate function. Instead of copying pages, only get a link to the page. This notable speeds up key searches on bigger tables. storage/maria/ma_write.c: Added comment storage/maria/maria_def.h: Moved page_cleanup() to separate function. |
